3. What is Climate Change
Climate is the aggregated pattern of weather,
meaning averages, extremes, timing, spatial
distribution of…
• hot & cold
• cloudy & clear
• humid & dry
• drizzles & downpours
• snowfall, snowpack, & snowmelt
• blizzards, tornadoes, & typhoons
Climate change means altered patterns.
Global average temperature is just one measure of the
state of the global climate as expressed in these patterns.
Small temperature changes big changes in the patterns.
(after Holdren NCES, 2008)
4. CLIMATE CHANGE causes:
Change in the length and cycles of the rainy
season;
Change in the intensity and frequency of rainfalls;
And brings about:
Calamities such as:
Heat waves
Drought
Violent storms
Devastating floods
Destruction of the environment
Sickness and death due to calamities
5. CAUSES OF CLIMATE CHANGE
CAUSED BY THE EFFECTS OF THE SUN
SUNLIGHT CARRIES ENERGY THAT WARMS UP THE EARTH. A BIG PART OF IT IS
DIRECTLY REFLECTED BACK TO THE ATMOSPHERE AND TO SPACE.
CAUSED BY THE EFFECTS OF HUMAN ACTIVITIES
MANY HUMAN ACTIVITIES INCREASE CARBON DIOXIDE AND OTHER GREENHOUSE
GASES CONTRIBUTING TO THE RISE IN GLOBAL TEMPERATURE WHICH CAUSE
CLIMATE CHANGE.
AS HUMAN POPULATION GROWS THE AMOUNT OF ACTIVITIES TO RESPOND TO THEIR
NEEDS INCREASES. THESE ACTIVITIES CAUSE THE WORSENING OF POLLUTION AND
THE INCREASE IN THE CONCENTRATION OF NATURAL AND SYNTHETIC GASES IN THE
ATMOSPHERE.
THE INTENSIFICATION OF GLOBAL WARMING IS ESTIMATED TO HAVE STARTED
AROUND THE END OF THE 18TH CENTURY AT THE ONSET OF THE INDUSTRIAL
REVOLUTION.
6. THE GREENHOUSE GASES
WATER VAPOR
THIS IS THE MOST ABUNDANT GAS IN OUR ATMOSPHERE THAT CAUSES CLOUD FORMATION, PRECIPITATION, AND
CONTROLS THE INTENSIFIED HEAT IN THE ATMOSPHERE.
INCREASED WATER VAPOR WARMER TEMPERATURE
CARBON MONOXIDE (CO) AND CARBON DIOXIDE (CO2)
COME FROM NATURAL PROCESS LIKE BREATHING AND VOLCANIC ERUPTIONS.
ALSO FORMED DURING THE BURNING OF FOSSIL FUELS.
HUMAN ACTIVITES LIKE CUTTING OF TREES, DEFORESTATION, FOREST FIRES, USE OF FOSSIL FUELS INCREASED THE
CONTRATION OF CARBON DIOXIDE IN OUR ATMOSPHERE.
CHLOROFLUOROCARBON (CFC)
USED AS REFRIGERANTS, AEROSOL PROPELLANTS
DAMAGES THE OZONE LAYER OF THE EARTH
METHANE
FORMED FROM NATURAL PROCESSES SUCH AS ORGANIC MATERIALS LIKE GARBAGE, MANURE AND RICE STRAW
NITROUS OXIDE
FORMED FROM THE USE OF COMMERCIAL AND ORGANIC FERTILIZERS, BIOMASS BURNING, FOSSIL FUEL
COMBUSTION AND NITRIC ACID PRODUCTION

NOT MATCH THE RISE IN
COST OF GOODS AND
SERVICES RESULTING TO
FEWER CONSUMPTION
• IF CONSUMPTION IS LOW,
BUSINESS AS WELL AS THE
ECONOMY WILL COLLAPSE.
9. POLICIES AND ROGRAMS ON CLIMATE CHANGE
POLICY/AGREEMENTS SALIENT FEATURES
R.A. 9729 as amended by
R.A. 10174 or The CLIMATE
CHANGE ACT OF 2009
• Aims to prevent and alleviate the harmful effects of climate change and to
ensure the safety of their area and its residents.
• Established the Climate Change Commission
• Paved the way for the National Climate Change Action Plan (NCCAP) and the
Local Climate Change Action Plan (LCCAP). The plans were outlined from 2011
to 2028 or a period of 18 years.
• The Action Plan included the following:
1. FOOD SECURITY
2. WATER SUFFICIENCY
3. ECOLOGICAL AND ENVIRONMENTAL STABILITY
4. HUMAN SECURITY
5. CLIMATE-SMART INDUSTRIES AND SERVICES
6. SUSTAINABLE ENERGY
7. KNOWLEDGE AND CAPACITY DEVELOPMENT
INTERGOVERNMENTAL
PANEL ON CLIMATE CHANGE
(IPCC)
• Established by the World Meteorological Organization (WMO) and the United
Nations Environment Programme (UNEP) in 1988
• The Intergovernmental Panel on Climate Change (IPCC) is dedicated to
providing the world with an objective, scientific view of climate change, its
natural, political and economic impacts and risks, and possible response
options.
10. POLICY/AGREEMENTS SALIENT FEATURES
INTERGOVERNMENTAL PANEL
ON CLIMATE CHANGE (IPCC)
• The IPCC was tasked with reviewing peer-reviewed scientific literature and
other relevant publications to provide information on the state of
knowledge about climate change
• The IPCC produces reports that contribute to the work of the United
Nations Framework Convention on Climate Change (UNFCCC), the main
international treaty on climate change.
• IPCC reports cover the "scientific, technical and socio-economic
information relevant to understanding the scientific basis of risk of human-
induced climate change, its potential impacts and options
for adaptation and mitigation.
• The IPCC provides an internationally accepted authority on climate
change, producing reports that have the agreement of leading climate
scientists and consensus from participating governments.
• The IPCC was awarded the 2007 Nobel Peace Prize which it shared with Al
Gore.
UNITED NATIONS
FRAMEWORK CONVENTION
ON CLIMATE CHANGE
(UNFCCC)
• The United Nations Framework Convention on Climate Change (UNFCCC)
is an international environmental treaty adopted on 9 May 1992 and
opened for signature at the Earth Summit in Rio de Janeiro from 3 to 14
June 1992
• The UNFCCC objective is to "stabilize greenhouse gas concentrations in the
atmosphere at a level that would prevent dangerous anthropogenic
interference with the climate system".
11. POLICY/AGREEMENTS SALIENT FEATURES
UNITED NATIONS
FRAMEWORK
CONVENTION ON CLIMATE
CHANGE (UNFCCC)
• The framework sets non-binding limits on greenhouse gas emissions for
individual countries and contains no enforcement mechanisms. Instead, the
framework outlines how specific international treaties (called "protocols" or
"Agreements") may be negotiated to specify further action towards the
objective of the UNFCCC
• One of the first tasks set by the UNFCCC was for signatory nations to
establish national greenhouse gas inventories of greenhouse gas (GHG)
emissions and removals.
• Major Treaties and Protocols:
1. KYOTO PROTOCOL - 2008-2012
2. DOHA AMENDMENT TO THE KYOTO PROTOCOL - 2013-2020
3. PARIS AGREEMENT
KYOTO PROTOCOL • The Kyoto Protocol is an international treaty which extends the 1992 United
Nations Framework Convention on Climate Change (UNFCCC) that commits
state parties to reduce greenhouse gas emissions, based on the scientific
consensus that:
• global warming is occurring and
• it is extremely likely that human-made CO2 emissions have predominantly
caused it.
• The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and
entered into force on 16 February 2005. There are currently 192 parties to the
Protocol.
12. POLICY/AGREEMENTS SALIENT FEATURES
KYOTO PROTOCOL • The Protocol's first commitment period started in 2008 and ended in 2012. A
second commitment period was agreed in 2012, known as the Doha Amendment to
the Kyoto Protocol, in which 37 countries have binding targets.
• As of September 2019, 132 states have accepted the Doha Amendment, while entry
into force requires the acceptances of 144 states. Of the 37 countries with binding
commitments, 7 have ratified.
PARIS AGREEMENT • The Paris Agreement is an agreement within the United Nations Framework
Convention on Climate Change (UNFCCC), dealing with greenhouse-gas-emissions
mitigation, adaptation, and finance, signed in 2016.
• As of March 2019, 195 UNFCCC members have signed the agreement, and 187 have
become party to it.
• The Paris Agreement's long-term temperature goal is to keep the increase in global
average temperature to well below 2 °C above pre-industrial levels; and to pursue
efforts to limit the increase to 1.5 °C.
• It also aims to increase the ability of parties to adapt to the adverse impacts of
climate change, and make "finance flows consistent with a pathway towards low
greenhouse gas emissions and climate-resilient development.
• Under the Paris Agreement, each country must determine, plan, and regularly
report on the contribution that it undertakes to mitigate global warming. No
mechanism forces a country to set a specific target by a specific date, but each
target should go beyond previously set targets
13. POLICY/AGREEMENTS SALIENT FEATURES
PARIS AGREEMENT • This strategy involved energy and climate policy including the so-called 20/20/20
targets, namely the reduction of carbon dioxide (CO2) emissions by 20%, the
increase of renewable energy's market share to 20%, and a 20% increase in energy
efficiency.
• The Paris deal is the world's first comprehensive climate agreement.
